Improved helium exchange gas cryostat and sample tube designs for automated gas sampling and cryopumping
In order to eliminate the use of liquid helium for the extraction of atmospheric gases from polar ice cores, two units of a redesigned top load helium exchange gas cryostat were built and tested. The cryostats feature the shortest and largest diameter sample wells built to date, a base temperature b...
